quality better in a constant bitrate but also help to calculate the capacity of the recording. VBR
means that the compression bitrate can be adjustable according to the change of the video
resources. This will help to optimize the network bandwidth.
Video Quality

quality you choose, the more bitrate will be required.
Bitrate

used in an an interactive application with low complexity and delay. Main profile is mainly
used for higher coding requirement.
Alarm picture size
: Please adjust accordingly.
Video encode slice split
